TECHNICAL FIELD

Embodiments of the present invention relate generally to vehicle safetymonitoring, and more particularly to video capture, user feedback,reporting, adaptive parameters, and remote data access in vehicle safetymonitoring.

BACKGROUND

Companies which control and operate vehicles, for example emergencyresponse vehicles, are often interested in knowing how safely thosevehicles are being operated, as well as identifying and documenting anyproblems with driver behavior. These companies may opt to provide theirdrivers with feedback during a driver safety violation, and may also optto document such information over time, in order to compile a reportabout individual drivers or the companies' drivers as a whole.Information about driver behavior and vehicle safety conditions may alsobe used to investigate vehicle crashes or other safety events after theyhave occurred.

Although vehicle safety monitoring systems can improve driving behavior,the types of driver feedback and the level of detail that can becollected for later use are relatively limited for emergency responsevehicles. Some such systems may collect video data related to particularsafety violation events, for example too rapidly accelerating ordecelerating. However, such systems are often incapable of collectingvideo data that has been triggered or flagged by conditions unrelated oronly partially related to the driver's behavior. Current vehicle safetymonitoring systems also often do not provide easy access to the datacollected on board the vehicle, and often do not permit dynamic creationof reports based on current and past vehicle safety data.

According to some embodiments of the present invention, theVDM 10 is a box, housing, frame, and/or enclosure which includes aprocessor and a memory with instructions for carrying out the VDM's 10functions as described herein, and which is communicably coupled tovarious devices and/or sensors within the vehicle 101, as well as to thenetwork 12, according to embodiments of the present invention.

According to embodiments of the present invention, the VDM 10 isconfigured to establish a vehicle record. The vehicle record may be aset of data stored locally in the mobile environment 101 and/ortransmitted via the network 12 to other environments for later storage,use, and integration with other vehicle records. The vehicle record mayinclude the status of one or more conditions at particular moments intime or over ranges of time. In addition to creating the vehicle record,the VDM 10 may also alert drivers or other crew members of the vehicle101 of particular situations, for example safety violations (actualand/or perceived), which may in some cases also be made part of thevehicle record. As such, all or a portion of the vehicle record may be avehicle driving safety record, according to embodiments of the presentinvention.

In situations in which all of some of the VDM 10 is a box, the box mayhave an outer structure that is impact resistant, fire resistant, and/orwater resistant and/or watertight, so that in the occurrence of a crashor other catastrophic event, the vehicle record stored on the VDM 10 maylater be recovered, similar to a “black box” for an airplane, accordingto embodiments of the present invention.

Data from the VDM 10 (and therefore data from the devices communicablycoupled with the VDM 10) may be received by one or more enterprisestorage servers 126 in an administration environment 103 and stored inan enterprise database 130, and the same information may be accessed andprovided by one or more enterprise application servers 128 to aworkstation 122 of an enterprise user 124, according to embodiments ofthe present invention. The database 130 may be multiple databases whichare linked; for example, vehicle speed data about a particular ambulancerun in one database may be linked with patient data for the patient whowas transported in another database, for example by a unique ambulancerun identification number, according to embodiments of the presentinvention. According to embodiments of the present invention, the VDM 10is communicably coupled to the storage server 126 which is communicablycoupled to the database 130, and the application server 128 iscommunicably coupled to the database and to the enterprise workstation122. Such devices may be communicably coupled via a network 12 such as,for example, the Internet.

When the VDM 10 receives updated information from one or more of thedevices to which it is communicably coupled, the VDM 10 sends theupdated information to the enterprise storage server 126, which storesthe updated information in a database which may be contained on astorage medium 130, according to embodiments of the present invention.Hence, information collected by the vehicle data manager may be storedin a mobile memory 406, 408 (see FIG. 4), remote enterprise database130, or both, according to embodiments of the present invention. Anenterprise user 124, who may be an emergency room nurse monitoringand/or preparing for ambulance arrivals, an emergency room physician,and/or a medical director at home, for example, may access informationsimilar to information collected by VDM 10 by requesting the informationvia an enterprise workstation 122. The enterprise user may also be adispatcher or supervisor or other personnel who monitors vehicleactivities, for example police or fire response personnel. For example,the enterprise workstation 122 accesses a web interface and/or thinclient web browser application which requests the information over thenetwork 12 from application server 128. Application server 128 queriesthe database 130 for the information, and returns a display toenterprise workstation, according to embodiments of the presentinvention. The application server 128 may be configured to stream datafrom the VDM 10, and/or to store data from the VDM 10, according toembodiments of the present invention.

According to embodiments of the present invention, the website displayin the enterprise environment 102 is accessed via a generic internetbrowser by a supervisor or dispatcher for one or more ambulances 101 orother emergency vehicles. The website may be secured by logon usernameand password, for example. Each ambulance may be identified by a vehiclename; the supervisor chooses from a list of incoming vehicles, afterwhich the data for that patient is displayed. The data may be shown justas it appears on the mobile screen, also in “clinical time.” The vehicledata manager 10 collects information about driver behavior and/orperformance, and sends the information, for example alerts aboutoverforce or overspeed conditions, to the enterprise user 124. Alertsabout driver performance issues or safety concerns may also be sent to auser via a mobile device 136, according to embodiments of the presentinvention.

According to yet other embodiments of the present invention, theenterprise user 124 is a vehicle fleet management operator, who accessesdata about the driving performance and vehicle maintenance or “wear andtear” information via the enterprise workstation 122, in order todetermine when maintenance should be scheduled, and/or the type ofmaintenance that may be recommended or necessary.

Although FIG. 1 depicts a single VDM 10 in the mobile environment 101,more than one VDM 10 may be used in the mobile environment 101 tocommunicably connect to the same or a different set of devices and/ordriver performance monitoring systems. And although FIG. 1 depicts onemobile environment 101, more than one mobile environment 101 and/or morethan one VDM 10 may be communicably coupled with the administrationenvironment 103 and/or the enterprise storage server 126, according toembodiments of the present invention, as illustrated in FIG. 7.According to embodiments of the present invention, the enterprisestorage server 126 receives vehicle data information from VDM 10 andstores it in database 130 along with an authenticated time stamp and anidentifier associating the information with a particular EMS crew memberand/or a particular EMS vehicle. In this way, data from multiplevehicles and/or multiple crew members and drivers may be accessed by theenterprise user 124.

As also illustrated in FIG. 1, the enterprise storage server 130 maysecurely store the information received from one or more VDMs 10 forlonger periods of time to permit later use of the information. Forexample, the VDM 10 may receive crew-identifying information such asname, address, employee number, and/or drivers license number via a crewmember ID device 14, and then may convey some or all of thecrew-identifying information to enterprise storage server 126 with arequest for the enterprise storage server 126 to query the database 130for past records involving the same crew member or vehicle. Theenterprise storage server 126 may then forward any such records orportions of such records back to the VDM 10 to permit the VDM 10 to makeany configurations and/or settings to the VDM 10. Similarly, such pastvehicle record information may also be accessed by the enterprise user124, according to embodiments of the present invention. A systemadministrator 134 may access and/or monitor the data in database 130and/or modify the instructions of the servers 126, 128 viaadministration workstation 132, which may be communicably coupled to theservers 126, 128, according to embodiments of the present invention. TheVDM 10 and server 126 may be configured to exchange data based onpriority, cost, and/or size, according to embodiments of the presentinvention. For example, important data may be communicated in itsentirety, while costlier or larger or less important data may bede-prioritized, or not communicated at all, between the VDM 10 andserver 126, according to embodiments of the present invention.

According to some embodiments of the present invention, the VDM 10transmits all vehicle record information to another device or devicesvia the network 12.

Camera position 2 is in the rear cabin 152, facing towardthe interior of the cabin 152. Camera position 7 is also in the rearcabin 152, facing toward the interior of the cabin 152. Other camerapositions are possible within the rear cabin 152. Camera positions 2 and7 are configured to capture within the video capture devices 26 fieldsof view the patient treatment area, and may be configured to receivevisual information (e.g. video frames) about the activities or status ofthe patient 116 and/or EMS technician 114, according to embodiments ofthe present invention. Camera position 3 is at or near the front of thevehicle, pointing generally in a direction of normal travel of thevehicle. Camera position 3 permits the video capture device 26 tocollect visual information about the front view of the vehicle, similarto what the driver 112 might see by looking out the windshield,according to embodiments of the present invention. Camera position 4 isat or near the rear of the vehicle 101, pointing generally in adirection opposite to normal travel of the vehicle, and permits videocapture device 26 to collect visual information about what is happeningbehind the vehicle, similar, for example, to what the driver 112 mightsee in the rear-view mirror. Camera position 5 is at or near the rightside of the vehicle 101, pointing away from the vehicle, and cameraposition 6 is at or near the left side of the vehicle 101, pointing awayfrom the vehicle. Camera positions 5 and 6 permit capture of visualinformation about what is happening outside the vehicle 101 on the sidesof the vehicle, according to embodiments of the present invention.Camera position 8 is inside the front cabin 150, facing out in the samedirection as the driver's eyes; this camera position 8 may be referredto as the driver's eye view. Numerous other camera positions arepossible for gathering various types of visual information, both insideand outside the ambulance. For example, a single camera may be mountedon the top of the vehicle 101 (not shown), and configured to rotate tovarious positions to capture the same information as camera positions 3,4, 5, and/or 6. As another example, a panoramic still camera or videocamera and/or camera with a spherical mirror may be mounted on the topof the vehicle 101 and configured to take photographs and/or video inthree-hundred sixty degree view, for later conversion to a panoramicand/or continuous image or video, according to embodiments of thepresent invention.

FIG. 7 illustrates various emergency vehicles 101 each with a VDM 10communicably coupled (e.g. wirelessly) to network 12, and illustrateshow an enterprise user 124 may receive vehicle data from multipledifferent vehicles 101, according to embodiments of the presentinvention. For example, a supervisor 124 for a group ambulances 101 maytoggle or cycle through the live or near-live video feeds from cameraposition 1 for each ambulance 101 to see what each driver 112 is doing,according to embodiments of the present invention.

A VDM 10 according to embodiments of the present invention creates avehicle record, for example a vehicle driving safety record, based onvarious types of information which may include, without limitation,driver identification information, seatbelt information, vehicle backinginformation, force information, and speed information, according toembodiments of the present invention.

The VDM 10 may be configurable to generate individual tone activations(e.g. on/off tone activations delivered through the audio device 42)which are user configurable. The VDM 10 may deliver various types oftones, for example a growl (e.g. clicking, or “Geiger counter” typesound), intermittent tone, steady violation tone, and voice messages.The intermittent and steady tones may vary in pitch. These tones may beapplied to all users, but the volume level may be customized by eachuser according to various versions of VDM 10. In some cases, the VDM 10may use growling tones and intermittent tones as warnings and reminders,while using steady tones to indicate violations. Voice messages may beutilized to describe a particular warning or violation, and/or todelivery user-defined messages to the crew.

According to some versions of VDM 10, the tone settings are configurablefor individual vehicles, groups of vehicles, and/or the entire fleet.For example, while a driver 112 of a particular vehicle 101 may be ableto customize the tone settings for that particular vehicle 101, anenterprise user 124 may be able to configure the tone settings for eachvehicle 101, groups of vehicles, and/or the entire fleet controlled viaenterprise workstation 122. According to some embodiments of the presentinvention, the driver 112 and/or crew member 114 may turn off anindicator light which is normally configured to convey warning alertsfrom the VDM 10.

According to some embodiments of the present invention, the user mayactivate with the VDM 10 an automatic audible feedback volume controlbased on vehicle speed, siren activation, and/or ambient noise level.For example, the user may configure the VDM 10 to increase the volume ofa message delivered via the audio device 42 based on the VDM 10 sensinga siren activation signal from the siren module 514, or based on the VDM10 sensing a vehicle speed (e.g. from either the speedometer module 516and/or the vehicle speed sensor 24) that is beyond a certain threshold.According to other embodiments of the present invention, the VDM 10adjusts the volume of such audio messages proportionally according tothe current speed value.

The VDM 10 may also include a driver identification routine or routines,according to embodiments of the present invention. The VDM 10 in someversions may permit driver logon at any time, and may confirm it with aconfirmation tone delivered via the audio device 42. The driver IDdevice 14 may be configured to accept an indication from a driver, forexample via a programmable driver ID tag that is unique to theparticular system 100, and optionally a user-defined unique locationidentification.

In some versions, the VDM 10 may assign all recorded vehicle and driverdata to the particular driver which is logged on when the data isrecorded, for the entire “run” during which the driver was logged in.The “run” ends when the currently logged on driver is logged off. Logoffoccurs when another driver is logged on to the system, when no ignitionsignal 526 signal is detected or no engine rotation signal 24 isdetected for a particular duration of time (for example one minute), orwhen the currently logged on driver logs off of the system. This systemlogoff may occur when the currently logged on driver performs anotherlogon procedure, for example by swiping the same card through a cardreader. The VDM 10 may then confirm the logoff with a tone, for examplea different tone or different tone pattern than the logon tone or tonepattern. This may be a double beep for logoff, and a single beep forlogon. The VDM 10 may retain in its memory the information about thecurrent driver through the entire vehicle mission or “run,” even in thevent of data downloads from VDM 10, uploads, and/or power failsituations.

According to some embodiments of the present invention, the driver maylog on to the VDM 10 system via a proximity device like an RFIDtransceiver, a biometric system, and/or an interface to another datasource that may already contain the information about the currentdriver, such as a crew scheduler software application. If a crewscheduler software application is used by VDM 10 to indicate the currentdriver, the VDM 10 may prompt the driver for confirmation before loggingon the driver, according to embodiments of the present invention.

According to some embodiments of the present invention, the VDM 10permits remote login through its connection with network 12. Forexample, a dispatcher, who may be using enterprise workstation 122, mayremotely log on a driver or a crew member into the VDM 10 system,according to embodiments of the present invention.

The VDM 10 may deliver via audio device 42 a voice message, or via videodisplay device 40 a video message, at the time of crew member logon.This message, as well as the options for its delivery, may beconfigurable by the user. For example, a particular driver 112 mayconfigure VDM 10 to deliver the greeting message to the particulardriver 112 only once per day, regardless of the number of times that thesame driver 112 logs on to the VDM 10 system, according to embodimentsof the present invention.

The content of such voice or video messages may also be customized toeach user and/or vehicle and/or situation. For example, once VDM 10determines a particular driver's identity, the VDM 10 may be configuredto deliver a voice message that says, “Welcome, driver. This isyour______login to this vehicle,” in which the VDM 10 fills in the blankwith a voice representation of a number of times which the same driverhas logged on to the same vehicle, for example “first” or “tenth” or“one hundred forty-seventh,” according to embodiments of the presentinvention. According to other embodiments of the present invention, theVDM 10 is configured to provide customized messages to the user based onthe user's classification, for example if the user is a supervisor, theVDM 10 says at login “welcome supervisor,” but if the user is not asupervisor, the VDM 10 plays at login “welcome driver.” This informationwhich the VDM 10 uses to identify whether the driver falls into aparticular class may be stored locally in VDM 10, stored remotely inremote database 130, and/or stored on the user's ID media, for examplethe user's RFID enabled identification badge. The VDM 10 may alsorecognize, based on the driver's identification or based on previouslystored information, that the driver's name is John Doe, and may beconfigured to deliver a greeting via audio device 42 that says “WelcomeJohn Doe.”

In addition to tracking the identity of the current driver, the VDM 10may also be configured to accept and track the identities of one or morecrew members. For example, a crew ID device 14 may be located in therear cabin 152 and permit a crew member to log in in a fashion similarto the driver login described above. A crew ID device 14 may also belocated on the exterior of the vehicle 101, for example on one or bothrear corners, to permit a spotter to identify him or herself while atthe same time indicating their presence and function as a spotter. Crewidentification data may also come to VDM 10 from another application,such as a crew scheduling software application either locally or onenterprise workstation 122, according to embodiments of the presentinvention. The crew identification and logon process may use the same ordifferent tone, voice messaging, and/or data recording as used for thedriver, according to embodiments of the present invention.

In some cases, if the VDM 10 detects the presence of ignition or an RPMsignal for the engine (for a customizable, or developer-defined,duration and/or combination of time and presence of a speed parameter),and there is no driver logged in, then the VDM 10 may log in an “unknowndriver” for the vehicle data record. The system functionality andreporting capabilities for the unknown driver may be the same as thosefor known drivers. In some versions, if the VDM 10 detects ignition oran engine RPM signal, and no speed, while the unknown driver is loggedon, the VDM 10 may deliver an intermittent tone. If speed is detectedwhile the unknown driver is logged on in such situations, a steady tonemay be sent through the audio device 42 by VDM 10.

According to embodiments of the present invention, the VDM 10 delivers avoice message concerning unknown driver activity, for example a voicemessage that says “Unknown driver” or the like. According to someembodiments of the present invention, the VDM 10 permits customizedsettings, for example for safety exception/violation reports and driveraudible feedback, based on the individual driver identity and/or thegroup or classification to which the driver is assigned. Suchclassification or individual identity may be obtained from the crew IDdevice 14 and/or obtained from an outside data source such as a crewscheduling system, according to embodiments of the present invention.For example, a supervisor may be able to drive at a higher speed than anon-supervisor, without an overspeed violation tone, and a driver havinga probationary classification, or an unknown driver, may have loweroverspeed settings than both the supervisor and non-supervisor or EMT,according to embodiments of the present invention.

The VDM 10 may also detect an attempted improper driver change andeither record or prohibit or warn against the change if a new driverlogin is received when the vehicle is traveling faster than apredetermined speed, according to embodiments of the present invention.

According to embodiments of the present invention, the VDM 10 tracksseatbelt data and/or seat sensor data for one or more seats. Forexample, the VDM 10 receives a signal from the seatbelt sensor 18 of thedriver 112, and sounds a tone when a vehicle speed is detected while thedriver's seatbelt is unfastened or unbuckled, or is unfastened orunbuckled for a user defined period of time. According to embodiments ofthe present invention, the VDM 10 plays a user customized voice messagevia audio device 42 when a seat belt violation is detected. According toother embodiments, the VDM 10 receives a signal from seat sensor 19indicating that an individual is seated in the particular chair, butreceives a signal from the corresponding seatbelt sensor 18 indicatingthat the seatbelt is not fastened for that particular chair, and basedon the determination provides an alert to the driver and/or theparticular user seated in the seat and/or another crew member, and/orrecords the seatbelt violation in the vehicle record. The VDM 10 maytrack the seatbelt status and seating status of each seat in thevehicle, and/or the safety straps and/or presence of a patient in thepatient cot, according to embodiments of the present invention. Sensingwhether a patient is in the patient's cot or whether the patient isproperly restrained in the patient cot may permit the VDM 10 to storedata that may be used to evidence compliance with a particularregulation, standard, and/or protocol. The VDM 10 may also be configuredto generate a warning message and/or record a safety exception in thevehicle record if the seatbelt is fastened before a user is detected inthe chair, according to embodiments of the present invention. The VDM 10may also interface with other third party systems, or the vehicle's onboard systems 20, which also detect the seatbelt and/or seating statusfor multiple seating positions, according to embodiments of the presentinvention.

The VDM 10 may also track what may be referred to as “backing”information for the vehicle 101. In large vehicles like ambulances, itis often difficult for the driver to see potential obstacles locatedbehind the vehicle, which must be avoided while backing up theambulance. Thus, a spotter may be advantageous, because the spotter maystand behind the vehicle and shout information and/or use hand gesturesto alert the driver of obstacles, or to direct the driver about whichway to turn or how fast to go. A vehicle 101 may include a spotterswitch 22. When the VDM 10 senses that the vehicle is in reverse drive,for example from a reverse activation signal 534, and if any vehiclespeed is detected for a certain amount of time (e.g. two seconds ormore), the VDM 10 may be configured to accept the activation of thespotter switch 22 for a user defined period of time before and after thestart of the reverse activation, and the switch activation may serve toindicate the activation for a user defined period of time, which mayeliminate the need for multiple switch depressions during subsequentback-and-forth backing maneuvers. This may be particularly beneficialfor a parallel parking maneuver, according to embodiments of the presentinvention.

The backing alerts and reporting activation criteria (for entry into thevehicle record) may be user configurable on a vehicle-by-vehicle basis.If the VDM 10 begins to implement the spotter logic, and does not detecta spotter switch 22 activation, an intermittent tone may be produced toremind the driver of the spotter requirement. Detection of the spotterswitch 22 activation may halt the tone. If the user-defined timeparameters expire during a detected backing occurrence, and if there hasbeen no spotter switch 22 activation, a steady tone for a limited lengthof time may be produced, indicating that a violation has occurred. Ifthe time parameter expires while the vehicle is still in reverse, theviolation tone may continue until the vehicle is taken out of reverse orthe spotter switch 22 is activated, according to embodiments of thepresent invention.

According to some embodiments of the present invention, a switch orother indicating device accessible from the driver's seat, or simply adetection of the reverse activity by the VDM 10, may activate a backingcamera, for example a video camera in position 4 in FIG. 6, which maysubstitute for an activation of the spotter button. Also, a user-definedvoice message or video message may be played in addition to, or insteadof, the tone activity for a backing violation, according to embodimentsof the present invention. According to other embodiments of the presentinvention, the backing parameters of the VDM 10 are configurable, forexample the VDM 10 may determine that a supervisor is logged as thecurrent driver, and then disable the backing warning systems andviolation recording. According to embodiments of the present invention,a crew member ID device 14 is placed at or near the back of the vehicle101, for example at or near the spotter switch 22, and is used by theVDM 10 to determine an identity of a crew member who is serving as thespotter.

The VDM 10 according to embodiments of the present invention may sensespecific forces (e.g. G-forces) experienced by the vehicle 101, and/orcalculate acceleration experienced by the vehicle 101, and determine aforce value based on the measurements and/or calculations. According tosome embodiments of the present invention, the VDM 10 uses theaccelerometer 16, which may be a dual- or triple-axis accelerometer, todetermine an instantaneous specific force being experienced by thevehicle 101. For this purpose, the accelerometer 16 may be rigidly fixedto the vehicle 101, such that any acceleration experienced by thevehicle 101 are also experienced by the accelerometer 16. Theinstantaneous specific force may include one force componentsubstantially aligned with the direction of normal travel of the vehicle101, for example the front-to-back direction. The instantaneous specificforce may also include a force component substantially perpendicular tothe direction of normal travel, for example the side-to-side direction.According to some embodiments of the present invention, the VDM 10receives from accelerometer 16, and/or determines based on signalsreceived from the accelerometer 16, an instantaneous specific force thatis a magnitude of the vector sum formed by the front-to-back forcevector component and the side-to-side force vector component. Thisinstantaneous specific force magnitude may be referred to as anaccelerometer specific force.

According to other embodiments of the present invention, the VDM 10receives from accelerometer 16, and/or determines based on signalsreceived from the accelerometer 16, an instantaneous specific force thatis a magnitude of the vector sum formed by the front-to-back forcevector component, and any side-to-side force vector componentexperienced while the speed of the vehicle is above a certain speedsetpoint. This “masking” of the side-to-side force vector componentbased on vehicle speed may assist VDM 10 in filtering “false” orundesired overforce readings caused, for example, by centripetal forceexerted on the vehicle 101 when the vehicle 101 is turning. As usedherein, the term “instantaneous” when applied to a force or speed orother measurement or value is used in its broadest sense to refer to aparticular value at the moment in time, and/or an averaged value overtimes at or near to the particular moment in time, and/or smoothedvalues over times at or near to the particular time. For example, theVDM 10 may use, when implementing its logic, an instantaneous specificforce magnitude that is determined from averaging accelerometer 16measurements made each ten milliseconds.

The VDM 10 may also determine actual vehicle 101 acceleration in adifferent way, for comparison with the accelerometer specific force(both of which may be expressed in distance per square second). The VDM10 receives high precision speed information from speed sensor 24, forexample in the form of pulses or “clicks” which may be counted overtime. As on example, a very high precision speed sensor may beconfigured to provide several thousand discrete pulses or clicks for agiven revolution of the drive shaft and/or axle and/or vehicle wheel.This permits the VDM 10 to determine an instantaneous speed of thevehicle 101, for example by measuring average time between pulses. TheVDM 10 may calculate a rate of change of the instantaneous vehicle speedto determine an instantaneous acceleration. Prefiltering may be used forthe accelerometer 12 and/or speed sensor 24 signals in order to smooththe signals, according to embodiments of the present invention.

According to some embodiments of the present invention, the VDM 10compares, for a particular moment in time or range of time, theaccelerometer specific force with the instantaneous acceleration, anduses the lower value of the two as the current observed acceleration ofthe vehicle. This may reduce the probability of obtaining “false” orundesirable overforce alerts or records when one device experiences ananomalistic spike based on activity unrelated to unsafe driving. Forexample, the accelerometer 16 may sense a spike in specific force if thevehicle 101 hits a bump in the road, while the instantaneousacceleration falls well within the acceptable range—using the lowerobserved acceleration value may prevent a warning tone and a violationrecord. The VDM 10 compares the current observed acceleration of thevehicle to a preset acceleration (or g-force) value. This presetacceleration or g-force value may be referred to as the “safe force.”The safe force may be similar to the SAFEFORCE® value as measured by theZOLL RescueNet Road Safety system, according to embodiments of thepresent invention. When the observed acceleration exceeds the safeforce, the VDM 10 may be configured to alert the crew member (e.g. thedriver), and/or create an entry in the vehicle record to reflect asafety violation.

According to some embodiments of the present invention, the VDM 10 isconfigured to warn the driver before the observed acceleration reachesthe safe force. For example, the VDM 10 may be configured to provide,through the audio device 42, a growling noise when the observedacceleration exceeds eighty percent of the safe force value. The VDM 10may be configured to escalate the growling noise to an intermittent toneindication when the observed acceleration exceeds ninety percent of thesafe force value, and may be configured to provide a loud steady tonenoise/alarm when the observed acceleration exceeds the safe force value,to indicate an actual violation, according to embodiments of the presentinvention. These ranges and/or tones may be customized, for example, thegrowling may indicate an observed acceleration of ninety to one hundredpercent of safe force, a steady tone may indicate an observedacceleration of 100 to 110% of safe force, and a strong tone or alarmmay indicate a severe overforce condition of over 110% of safe force,according to embodiments of the present invention.

According to other embodiments of the present invention, the VDM 10 maybe configured to implement a “grace period” before warning a driverand/or recording a safety exception in the vehicle record. For example,the VDM 10 may be configured to identify a particular condition only ifthe condition is maintained for a particular amount of time, for exampleat least a half second. According to other embodiments, the VDM 10 isconfigured to provide to the user a voice message, video message, orother indication that the user is about to be warned of, and/or reportedas, violating a safety rule, and to give the user a certain amount oftime to correct the perceived safety violation.

According to embodiments of the present invention, the user (e.g. thevehicle fleet manager) may define force settings or values aspercentages of the safe force. For example, the user may define awarning range, a low overforce range, and a high overforce range. Whenthe observed acceleration reaches the warning setting, the VDM 10produces a growl (e.g. through audio device 42). As the force levelincreases, the frequency of the growl may increase (from slow to fast),until a low overforce setting is reached. When the low overforce settingis reached or exceeded, the VDM 10 may produce a steady tone for theduration of the low overforce occurrence. When the observed accelerationreaches or exceeds the value of the high overforce setting, the VDM 10may produce a tone of a higher frequency during the entire time when thehigh overforce condition is detected. According to some embodiments ofthe present invention, the VDM 10 causes a growl to be produced for atleast one second, to indicate a warning before noting any violation.

According to some embodiments of the present invention, the warning andoverforce ranges may be configurable, for example configurable based onthe driver's identity. The VDM 10 may determine the driver's identityvia the crew ID device 14, and then set the warning and overforce rangesaccordingly. For example, when the driver 112 is determined to have avehicle maintenance personnel classification, the VDM 10 may beconfigured to raise the warning and overforce settings much higher tofacilitate vehicle problem diagnosis by the driver.

The VDM 10 according to some embodiments of the present invention isalso configured to monitor vehicle speed, and in overspeed conditions tonotify the driver and/or crew, and/or to record a violation in thevehicle record. The VDM 10 may be configured with different settings foremergency and non-emergency driving. For example, emergency driving maypermit higher safe force values that non-emergency driving. Theemergency driving setting may be activated with a button or switch. Forexample, the VDM 10 may be configured to enter the emergency drivingsettings when it detects that the emergency lights 504 and/or sirens 514have been activated. According to some embodiments of the presentinvention, the VDM 10 may be configured to accept a remote command, forexample from a dispatcher 124 via an enterprise workstation 122, toactivate or de-activate emergency driving settings. For example, whenthe dispatcher 124 sends out an EMS response command via enterpriseworkstation 122, and a particular vehicle 101 indicates (for example inits navigation system 30) that it is responding, the authorization toVDM 10 to enter emergency driving status may be received either with theinitial dispatch, or via a subsequent automatic or manual activation bythe dispatcher 124 via workstation 122.

Emergency and non-emergency driving settings may include varioussettings, similar to the safe force settings. For example, the VDM 10may be configured to act upon an overspeed setting, a high overspeedsetting, and a duration setting. The overspeed and high overspeed valuesmay be set as either a maximum speed (e.g. in miles per hour orkilometers per hour). According to some embodiments of the presentinvention, the VDM 10 receives location information and/or posted speedlimit information from the navigation system 30, in order to determinethe posted speed limit at the current vehicle 101 location. Theoverspeed and high overspeed values may alternatively be set as a valueby which the driver may exceed the posted speed limit, or the assignedspeed limit for the particular road classification (e.g. highway, dirtroad). The VDM 10 accessing base speed limit information from a mappingdatabase, for example the mapping database of navigation system 30and/or other database accessible via network 12, may be referred to asdynamic overspeed determination. The VDM 10 may be configured to measurea duration for which a particular overspeed condition has been observed,and may also be configured to accept a particular overspeed durationsetting.

When the vehicle 101 is operated in the overspeed range, the VDM 10 maycause an audible growl to be emitted. If the overspeed time exceeds theduration setting, the VDM 10 may change the audible growl to an audibleviolation tone, and may continue the tone until the vehicle 101 speeddrops below the overspeed setting, according to embodiments of thepresent invention.

When the vehicle 101 is operated in the high overspeed range, the VDM 10may be configured to cause a tone at a higher frequency, for examplewithout any duration setting or grace period. The tone may continueuntil the speed drops below the high overspeed setting, but may remaintoning at a lower frequency if the vehicle is still in an overspeedcondition, according to embodiments of the present invention.

According to some embodiments of the present invention, the VDM 10 maybe configured to provide a voice message and/or video message toindicate to the driver an overspeed, high overspeed, and/or grace periodcondition. According to some embodiments, speed settings may beconfigurable based on driver identification. For example, new drivers,inexperienced drivers, or drivers who are new to the particular vehicle101, may have lower configured overspeed settings than more experienceddrivers.

The VDM 10 may provide alerts to the driver for other conditions, forexample, an indication that the vehicle 101 is in motion with theparking brake on. The VDM 10 may also include an audio output port tointerface with other OEM and/or aftermarket audio systems, for exampleFirecom® communications systems. According to some embodiments of thepresent invention, the VDM 10 may be configured to provide seatbeltstatus information via the video display device 40. The VDM 10 may alsobe configured to provide a visual force indicator via the video displaydevice 40; for example, the VDM 10 may use colors and/or shapes toexpress a magnitude of overforce and/or overspeed violations (e.g. redfor high overforce, yellow for low overforce, and green for noviolation). A visual force indicator may also be used that is not partof a video display device 40; for example, an LED panel mayprogressively light up additional LEDs as the force gets higher, and maychange color to the overforce or high overforce conditions, or overspeedand high overspeed conditions.

The VDM 10 may also perform other roles, for example providing a voicemessage via video display device 40 if it determines that the vehicle101 has been idling for an excess (e.g. user-defined) period of time.This may be detected by the VDM 10 receiving a signal that the ignition526 is active, while receiving a zero speed signal from the speed sensor24 for the particular period of time.

The VDM 10 may also be communicably coupled to one or more panicbuttons, which activate an alarm when pushed or activated. Such buttonsmay be configured to notify the VDM 10 to activate the light system 36,sirens 514, emergency lights 504, lighting system 532, and/or othersystems, according to embodiments of the present invention. The VDM 10may also be configured to provide voice messaging and/or video messagingto the crew to alert the crew to a potential maintenance concern withthe vehicle 101 based on signals from the internal on board diagnosticssystem 20, for example low oil pressure, high coolant temperature, highbrake temperature, check engine signal, and the like. The VDM 10 mayalso be configured to monitor maintenance-related info, both withrespect to time and over time, such as distances driven, active enginetime, and engine distance.

The VDM 10 may also be configured to provide user-defined voice messagesand/or video messages for user defined events that are not related tovehicle operation, for example a reminder to gather all equipmentfollowing an EMS response. The VDM 10 may also be configured to providedriver notification, as well as log in the vehicle record, other typesof driving violations. For example, the VDM 10 may be communicablycoupled to a proximity sensor at the front and/or rear of the vehicle101, and may be configured to monitor whether the vehicle 101 is tooclose to a vehicle in front (e.g. “tailgating”) or a vehicle behind. TheVDM 10 may be communicably coupled with a vibration sensor or othersensor capable of determining whether the vehicle 101 is veering orcommitting lane departure, and warn the driver and log the conditionaccordingly. The vibration sensor may be used, for example, to determinewhether one or more of the wheels is driving over the shoulder warningtrack.

According to some embodiments of the present invention, the VDM 10permits real time voice over IP messaging, for example via network 12.The driver 112 may communicate with a dispatcher 124 with back-and-forthvoice communications via VDM 10, which may include both live voicecommunications and/or prerecorded and prompted (either automatically ormanually) voice messages. Such audio communication may be accomplishedvia audio device 42, and/or via the sound system or radio 510 of thevehicle 101, according to embodiments of the present invention.

With its communicable coupling to network 12, the VDM 10 may also beconfigured to provide both local (LAN) and remote (WAN) communicationsof data, including ad hoc requests for the vehicle data record orportions thereof, as well as continuous streaming or real-timecommunication of vehicle record data. The VDM 10 may permit a user todownload and upload data via an existing Wi-Fi network, for example byincluding a Wi-Fi card as part of the VDM 10, according to embodimentsof the present invention. The VDM 10 may also permit a user to downloadand upload data via cellular connection to a cellular data modem or aircard; according to some embodiments of the present invention, the VDM 10utilizes and manages cellular communications through its own cellular“dongle” and/or SIM card. This functionality may be accomplished, forexample, by using a wireless EMS communications interface device withthe VDM 10, for example those described in Patent Cooperation TreatyApplication Serial No. PCT/US11/31868, filed on Apr. 9, 2011, which isincorporated by reference herein in its entirety for all purposes.

According to embodiments of the present invention, the VDM 10 mayinterface with, and/or be communicably coupled with, multiple device andapplications for the purpose of sharing data, for example via Ethernetand Wi-Fi connections. For example, the VDM 10 may interface with thenavigation system 30 as described above to obtain road segmentinformation in order to set dynamic overspeed conditions. The VDM 10 mayalternatively carry mapping information internally, to enable dynamicoverspeed determinations. In some cases, the mapping information storedon VDM 10 may be periodically updated via network 12. The VDM 10 mayalso be configured to determine and/or note in the vehicle recordwhether the vehicle 101 is within a school zone, according toembodiments of the present invention.

The VDM 10 may also be configured to provide data to other applications,for example an EMS data management suite, for example ZOLL RescueNet®.This may be done by cellular connection, for example, or by 900 MHzradio which may communicate through a serial connection, to download andupload data. The VDM 10 may serve as a Wi-Fi hotspot, enabling otherapplications to utilize the VDM's cellular or other connectivity; theVDM 10 may also communicate with other devices via Bluetooth®.

According to some embodiments of the present invention, a user (forexample a dispatcher) may connect to the VDM 10 via Wi-Fi, cellular,and/or USB hard wire and view the status and values of all (or anysubset of specified) monitored and controlled vehicle and driveractivities in real time. The VDM 10 may continue to monitor and controlnotifications even during communications, including downloading anduploading of vehicle record data. The VDM 10 may communicate with thevehicle computer (for example using OBDII and J protocols), and may sendrequests for data to the vehicle computer system 20, according toembodiments of the present invention. The VDM 10 may be configured tocommunicate with vehicle computer systems 20 made according to thestandards in various international markets, including the UnitedKingdom, Europe, South America, US, and elsewhere. The VDM 10 may alsobe user configurable to prioritize and schedule Wi-Fi and cellularcommunications, so as to minimize the impact to cellular bandwidth. Forexample, the VDM 10 may be configured to communicate via network 12during non-peak cellular usage hours.

The VDM 10 may also be configured to enhance a user's experience wheninteracting with the system 100. For example, the VDM 10 software may bewritten to an enterprise data store, for example data store 130.Back-end database 130 may store such data about the vehicle record fromVDM 10, and such data may be accessed with a certain set of services,for example proprietary or open web services, according to embodimentsof the present invention. protocols, in order to provide a webapplication accessible from enterprise workstation 122, personalcomputers, smart phones, iPads®, and other devices with internetconnectivity, via encrypted secured connections. The applicationsoftware for accessing the VDM 10 data may reside on the end user'sserver and/or a server hosted by the VDM 10 manufacturer, according toembodiments of the present invention. The system administrator 134 forsystem 100 may control the quantity and the specified serial numbers (orother unique identification numbers) of the VDM 10 devices supported bythe application. The system administrator 134, via the enterpriseenvironment 103, may also control the number of drivers that the systemwill support. For example, the enterprise user 124 may obtain from thesystem administrator 134 the rights to have the data from up to five VDM10 devices accessed via enterprise workstation 122. If the enterpriseuser wanted to add a sixth VDM 10 to the web interface system, theenterprise user would need to obtain activation from the systemadministrator 134, according to embodiments of the present invention.

The enterprise environment 103, including enterprise application server128 and enterprise storage server 126, may be configured to enable anddisable specific functions within the application program, and set timeparameters for the expiration of specific functions or operability. Theapplication program may be password protected, enabling users to assignspecific access and control levels to various multiple users. The systemadministrator 134 may be given an override and/or “back door” access tothe application program in the enterprise application server 128, forexample. For example, if the VDM 10, or the enterprise user 124,discovers that the vehicle 101 associated with the VDM 10 has beenstolen, the enterprise user 124 may remotely disable the vehicle, forexample by sending a command via VDM 10 to end the engine ignition 526,according to embodiments of the present invention. The VDM 10 may beconfigured with a battery power source, and upon receiving an indicationof having been stolen or lost, the VDM 10 may continue to power itselfand the GPS 32, so as to permit location of the stolen or lost vehicle101 using VDM 10, according to embodiments of the present invention.

The enterprise application server 128 may also be configured to providea “safety report,” which may display distance, low overforce, highoverforce, low overspeed, high overspeed, seatbelt violations, and/orbacking incidents according to driver and/or vehicle. A grade level maybe assigned to each vehicle or driver. The level assigned to eachvehicle or driver may include determining the level according to thefollowing calculations. The miles driven may be divided by a number ofcounts to arrive at the score. Each second in an overforce or overspeedcondition may equal one count, and each second in a high overforce orhigh overspeed condition may equal a user-defined number of counts. Eachunsafe backing occurrence may equal a user defined number of counts. Ifthe calculated score is greater than 250, then the level 10 may beassigned to the particular driver or vehicle. If the calculated score is128 to 250, then level 9 may be assigned; if 64 to less than 128, thenthe level 8 may be assigned; if 32 to less than 64, then the level 7 maybe assigned; if 16 to less than 32, then level 6 may be assigned; if 8to less than 16, then level 5 may be assigned; if 4 to less than 8, thenlevel 4 may be assigned; if 2 to less than 4, then level 3 may beassigned; if 1 to less than 2, level 2 may be assigned; and if less than1, level 1 may be assigned, according to embodiments of the presentinvention. FIG. 13 illustrates an example of a driver safety report asit may be displayed by server 128 via a remote internet interface,according to embodiments of the present invention.

The safety report may display the drivers or vehicles above or below auser-defined standard line, based on level, and/or display fleet ordriver totals, according to embodiments of the present invention. If adriver has zero counts, then the score level may be displayed as themiles driven multiplied by a factor of two, with a minimum level scorethat correlates to the minimum value of which the standard line isplaced (for example, if the driver drove 2.3 miles and had no counts,and the standard line was set at level 5, that driver's score would be8.0, putting the driver just over the standard line). The safety reportmay display total driving, emergency driving only, non emergency drivingonly, and may also have the ability to mask the drive name, for exampleby displaying only each driver's unique employee number or otheruser-defined identification. The safety report may also be sortablealphabetically and/or by the level score.

The enterprise application server 128 may also be configured to providea “grading report,” which may permit the user to specify specificoccurrences and events, and the data values attributed to suchoccurrences and events. For example, the user may wish to create a“green report” that grades driver performance as it relates to speed,forces, throttle position, oxygen sensor values, and idle time, whichare all factors which tend to have a higher degree of relevance to theenvironment.

The enterprise application server 128 may also be configured to providea “second-by-second report,” which may display a user-defined dateand/or time period, and resolution of all monitored inputs andindicators in a graphical format, with time being the horizontal axisand the value and description of the input displayed on the verticalaxis.

The application software mayalso turn off driver feedback messaging and/or tones with a remotecommand, according to embodiments of the present invention. For example,if the VDM 10 sends an alarm to the remote web application interfaceindicating that a smoke detector 23 has detected smoke in the frontcabin 150, the application software may display the smoke alarm to webinterface user 124. The web user 124 may access a live video stream, forexample from camera position 1, and observe that the driver 112 issmoking a cigarette. The web user 124 may turn off the smoke alarm, andsend the driver 112 a voice and/or video message instructing and/orreminding the driver 112 that smoking is not permitted, according toembodiments of the present invention.

According to some embodiments of the present invention, the user, forexample a vehicle fleet manager, may set monitoring, audible feedback,violation, grading, and reporting parameters for individual vehicles,groups of vehicles, and/or an entire fleet. Alternative parameters maybe specified for situations during which the vehicles 101 are operatingin emergency mode, and/or for different identified drivers.

An enterprise user 124 may view high resolution video images showing adriver's eye view, including images taken in low lighting conditions,with a minimum of a 120 degree field of view, out of the front windows(e.g. similar to camera position 8 of FIG. 6), according to embodimentsof the present invention. According to some embodiments of theinvention, the cameras have a field of view at or between thirty degreesand three-hundred sixty degrees. The enterprise user 124 may also viewhigh resolution, low light, video images of the front of the ambulance,with capability for viewing the driver and an attendee, similar tocamera position 1 of FIG. 6. According to some embodiments of thepresent invention, the VDM 10 collects from video capture device 26 (ormultiple video capture devices 26) at least forty-eight hours of videofootage without overwrites, such that if overwrites occur, the mostrecent images will be saved and the oldest images will be overwritten.Other time frames for video footage capture may be used, instead offorty-eight hours. According to embodiments of the present invention,the user 124 of the web application interface may view video imagesremotely in near real time. The enterprise application server 128 and/orenterprise storage server 126 may be configured to record and save allactivities when VDM 10 senses the presence of vehicle ignition and/orspeed. The user 124 may view video from one or more camera positionswhen the vehicle 101 is not running, but is otherwise triggered by auser-defined event, such as accelerometer activity.

According to some embodiments of the present invention, the VDM 10 tagsor flags or otherwise marks in the vehicle data record the occurrence ofa particular activity or combination of activities. These flags permit auser, for example web application user 124, to quickly locate data ofparticular interest, either in real time, or when reviewing the vehicledata record. According to some embodiments of the present invention, theVDM 10 write protects the data corresponding to flagged events toprevent the VDM 10 from writing over such data. For example, if a highoverforce condition is detected at 11:09 am, the VDM 10 write protectsall data corresponding to 11:09 am, and/or all data corresponding to11:08 am to 11:10 am, and/or certain kinds of data corresponding to aparticular time range. The user 124 may also view images taken from theback of the vehicle, for example from camera position 4, displayingbacking incidents, loading of patients, and/or rear-end collisions,according to embodiments of the present invention. The driver 112 may beable to view video images in real time taken from the rear of theambulance to facilitate vehicle backing (e.g. camera position 4). Thedriver may also be able to view video showing adjacent lane activity inreal time, for example images or video taken from video capture devices26 in one or more of camera positions 5 and 6, according to embodimentsof the present invention. The user 124 may also be able to view visualinformation taken from a rear cabin 152, for example from camerapositions 2 and/or 7. The user 124 may be a medical professional, andmay view visual information from the patient compartment 152 remotely inorder to provide telemedicine or other remote medical advice and/ordiagnosis, according to embodiments of the present invention. The rearcabin 152 may also be configured with two-way video capability for thispurpose, according to embodiments of the present invention. The VDM 10may also identify weather conditions, for example based on windshieldwiper use, and other external conditions, according to embodiments ofthe present invention.

The VDM 10 permits video images to be downloaded via Wi-Fi and/orcellular connections, and may select transfer times of such content,taking into account bandwidth, cost, and/or time information.Downloading of video images from VDM 10, for example by enterprisestorage server 126, may be toggled between low and high resolution, tofacilitate download via cellular network (e.g. for live remote viewing)or Wi-Fi (e.g. for large bandwidth transfer of video images for laterviewing). The web application interface provided to user 124 may permiteasy access to view video from time stamped or flagged activityreferenced from system reports, including tagged activity from adriver-activated panic button. The user 124 may be able to access andview video seamlessly from the web application interface program. As theuser 124 is viewing video or image content, the user may be able totoggle on or off the overlay of other data gathered by VDM 10, forexample the vehicle speed, whether emergency driving is activated, andthe like.

According to some embodiments of the present invention, the user 124 mayview a map while viewing video footage, such that the map indicates thevehicle 101 location corresponding to the timing of the video footage.The user 124 may move a representation of a vehicle 101 to variouspositions along the map in order to scroll to a different positionwithin the data. For example, a user 124 watching video footage from avehicle's data record may click on a little ambulance icon displayedover the map of the particular route and move it forward along theroute, and then unclick the ambulance icon to begin playing videocorresponding to the new ambulance icon location along the route. Themap display of the route may also include visual indicators that may betoggled on and off, the visual indicators illustrating flagged events.For example, the map may display little red flags at locations along thevehicle route at which overspeed and/or overforce conditions, or otherconditions, were logged in the vehicle data record. In such situations,clicking on one of the flags (which may be a visual representation otherthan a flag shape) retrieves and displays vehicle data corresponding tothe particular point in time that was flagged, for example video footageand/or recreation of a vehicle speedometer, according to embodiments ofthe present invention. Such information may be output, or suchinformation access cues may be interpreted, in other ways; for example,via voice command, retinal scan, or hand gesture, according toembodiments of the present invention.

The VDM 10, as well as the back-end servers 126, 128 and associatedprogramming, may be configured to facilitate the incorporation of datafrom multiple base station application programs, for example byassigning a location identifier to all records, according to embodimentsof the present invention. The application server 128 may be configuredto permit a user 124 to build “favorites” screens, in order to defaultor permit easy recall of commonly viewed screens and/or reports,according to embodiments of the present invention. The VDM 10 may alsobe configured to detect the presence of “shore power,” a power sourceexternal to the normal mobile power source of vehicle 101, and determineto keep certain devices or connections active in the presence of shorepower that would not normally be kept active when vehicle ignition isnot present, according to embodiments of the present invention.

According to some embodiments of the present invention, the VDM 10determines the existence of a particular condition based on visualinformation received from one or more video capture devices 26. Forexample, the VDM 10 may be configured to perform gesture recognition, todetermine when an intravenous line is being placed into the patient inthe rear cabin 152, or to determine when a person is standing up in therear cabin 152. Such determinations may trigger a separate data entryinto the vehicle data record, and/or may be used by VDM 10 incombination with other signals to determine triggering or flaggingevents. Such determinations may also be used by the VDM 10 to impact thealerts or warnings delivered to drivers 112 and/or crew members 114; forexample, the VDM 10 may be configured to lower the overforce settingsuch that a lower observed acceleration (e.g. lowest of accelerometer orvehicle speed change rate acceleration) is implemented when a VDM 10determines that a person is standing in the rear cabin 152; this dynamicoverforce or overspeed determination may help to warn the driver 112against undertaking a normally safe acceleration event that has becomepotentially less safe due to the fact that a person is standing up inthe rear cabin 152, according to embodiments of the present invention.The VDM 10 may also use video data to incorporate “machine vision” orthe like, in order to facilitate red light detection, lane departuredetection, tail gating detection, and seat belt compliance, for example.The VDM 10 may also be configured to dynamically adjust overforceparameters based on vehicle weight sensors, for example lowering theoverforce parameter for a left turn if the vehicle is heavier on theright side. As another example, airport crash rescue trucks, whichbecome top-heavy when they are loaded with water, may have theiroverforce and overspeed parameters lowered (for example based on thewater level) in order to deter potential vehicle rollovers. As anotherexample, if the VDM 10 detects a low tire pressure, it may dynamicallylower the overspeed limit. If the VDM 10 detects that the roads are icy,it may also lower the overspeed limit and overforce limit, according toembodiments of the present invention.

The VDM 10 may also use other sensors and/or devices within vehicle 101to determine the presence of certain conditions, for example, the VDM 10may infer that it is raining outside if a windshield wiper 506activation signal is received for longer than a predetermined period oftime (e.g. longer than a normal windshield cleansing cycle). The VDM 10may infer that it is dark outside if the headlights 502 are activated,according to embodiments of the present invention.

According to some embodiments of the present invention, the database 130includes a national database of driving scores for individual drivers,which may be accessed by one or more subscribers 124 to research aparticular driver's driving history. The enterprise application server128 may also be configured to provide a vehicle burden score, in orderto assist enterprise users in optimizing deployment; for example, if aparticular vehicle 101, such as an ambulance, has experienced a highamount of wear, it may be deployed for shorter trips than an ambulancethat is newer or has just had maintenance performed on it. As such, theapplication through which an enterprise user 124 interacts with thevehicle record data may permit correlation of scheduling data withvehicle 101 performance and/or maintenance-related data.

The enterprise application server 128 may also be configured to trackthe particular data and/or types of reports accessed by a particularenterprise user 124 and/or a subscribing organization (e.g. a particularcounty's fire department), and suggest to the user 124 one or more otherreports that are similar, or which similarly-acting users often access.The server 128 may be configured to identify trends in data usage,and/or in the data itself, and displays such trends in textual and/orgraphical format. The server 128 may also be configured to displaysuggestions or recommendations based on trends. For example, if server128 notices a relatively high number of backing violations, the server128 may include a graphical button that, when activated on the user's124 workstation 122, automatically activates a voice message for play byeach VDM 10 in the fleet on vehicle ignition, that says “please rememberto use a spotter when backing.”

The VDM 10 may also be configured to provide a reward and/or incentivesystem for drivers 112 or crew members 114, according to embodiments ofthe present invention. For example, when a driver 112 logs in to aparticular VDM 10 via crew ID device 14, and the VDM 10 queries database130 and determines that the driver 112 has a driving safety score thatexceeds a user-defined threshold, the VDM 10 may activate the soundsystem or radio device 510 for entertainment between runs, may activatea seat warmer system, an air conditioning or heating system, or otherentertainment or luxury items that are normally optional, but which maybe activated as a reward for safe driving. When a driver 112 logs in tothe VDM 10, the VDM 10 may display (e.g. via video display device 40 orvia a web browser interface when the driver 112 accesses data from aremote workstation 122) a graphic or point reward interface, which mayalso permit the driver to use points gathered for safe driving scores toredeem prizes or vacation time, according to embodiments of the presentinvention. The VDM 10 may also be configured to activate a Wi-Fi hotspot for internet access, as a reward for certain safety performance,according to embodiments of the present invention.

According to embodiments of the present invention, a user 124 may be acode reviewer reviewing the vehicle data record, and/or the patienttransport record. In such cases, the web application through which theuser 124 accesses the vehicle data may permit the user 124 to flag timesand/or events which were not previously flagged, for later retrievaland/or for facilitated review. In some cases, the user 124 may be adriver 112 and/or crew member 114, and the web application mayauthenticate their identity and permit them to review the vehicle datafor the runs which they have performed, and/or for the records whichinvolve their performance. According to embodiments of the presentinvention, the web application may permit the driver 112 and/or crewmember 114 to insert annotations or flags into the vehicle data record,for example for explanatory purposes. For example, if the VDM 10 addedto the vehicle data record an overforce condition, the driver 112 may beable to go back into the record and add a comment or annotation, whichmay be in the form of a recorded voice message, a text entry, a flag,and/or the like, to explain that the overforce condition was a result ofbraking to avoid colliding with another driver who was driving unsafely.According to some embodiments of the present invention, the enterpriseworkstation 122 is in the vehicle 101, and the driver 112 and/or crewmember 114 may edit and/or comment on the vehicle data record shortlyafter a particular run or a particular shift, while the events are stillfresh in memory. Such edits and/or comments may be added directly to thevehicle data record in VDM 10, and/or added to the remote copy of thevehicle data record stored on database 130, according to embodiments ofthe present invention. The crew member 114 and/or driver 112 may havethe ability to delete sections of video under certain circumstances.

According to some embodiments of the present invention, the VDM 10 isconfigured to receive commands via the audio capture device 28, and/orto transcribe narratives received via the audio capture device 28. Forexample, the driver 112 says “I am going to give a narrative now,” andthe VDM 10 interprets this as a command to begin voice-recognizedtranscription and/or to create a sound file (e.g. a “.wav” file) toenter into the vehicle data record the information recorded. Accordingto some embodiments of the present invention, the VDM 10 uses bothgesture and voice command recognition, for example recording a crewmember's narrative while flagging and/or bookmarking the points in timewhen the crew member makes a certain hand gesture, for example raisinghis or her hand.

According to some embodiments of the present invention, the VDM 10 isconfigured to build historical data, and/or to feed it back into theVDM's 10 feedback and alert system. For example, if VDM 10 senses anoverforce braking event along a particular stretch of road auser-defined number of times, the VDM 10 may automatically adjust theoverspeed limit to be lower to ensure that the VDM 10 reminds the driver112 to slow down going over that stretch of road, in order to avoidadditional braking events, according to embodiments of the presentinvention. Such historical data may also be used by VDM 10 to find aneffective speed limit for a particular stretch of road, and/or provide avoice alert, according to embodiments of the present invention.

The VDM 10 may be configured to store data in a recognized or industrystandard data format, for example National EMS Information System(NEMSIS) data format, HL7 format, or XML format, and/or the enterprisestorage server 126 may be configured to convert the vehicle record datafrom database 130 into a NEMSIS data format, according to embodiments ofthe present invention

According to some embodiments of the present invention, the VDM 10 isconfigured to gather vehicle data that may be used for fleet maintenancedecisions; for example, the reporting feature of enterprise applicationserver 128 may be configured to associate vehicle safety data withmaintenance data or decisions, for example activating a maintenancealert to an enterprise user 124 for a particular vehicle 101 earlier ifthat particular vehicle 101 has experienced more overforce conditions(e.g. heavy braking) than an average vehicle. The VDM 10 may also beconfigured to predict in-field failure, for example if a severe drop inbattery charge is detected for the vehicle 101, the VDM 10 may beconfigured to alert the driver 112 and/or crew 114 that a newdestination should be selected and/or a backup plan implemented.

According to some embodiments of the present invention, theadministration environment 103 collects vehicle data for numerousvehicles owned by multiple different vehicle fleet managers, and theenterprise user 124 is a member of the vehicle manufacturing orinsurance industry, who accesses via enterprise workstation 122 some orall of the vehicle data records in order to improve vehicle safetydesign, and as empirical or “real world” testing data for evaluatingvehicle performance over time and under various circumstances. In suchcases, any medical or patient or other confidential information may bescreened or shielded, but vehicle information may be passed through sucha connection in order to permit the user 124 to see historicalmaintenance and vehicle performance data for one particular vehicle orany number of vehicles over a particular period of time. Such reportsmay be interactively customized, permitting the user 124 to select theparticular field and time frames to view, according to embodiments ofthe present invention. The web data interface for manufacturing andinsurance industry participants may be customized to permit access todata fields that are of particular interest to those industries, forexample accelerometer-based information, seatbelt data, weightdistribution, tire pressure, engine diagnostics, and the like.

According to some embodiments of the present invention, the VDM 10 isconfigured to facilitate compliance with wearing hearing protection insituations in which hearing protection is required, by requiring a userconfirmation that hearing protection is secured, and/or by processingvideo imagery to determine whether a user is wearing earmuffs, forexample. The VDM 10 may also be configured to perform active noisecancellation, for example on siren sounds received through audio capturedevice 28, according to embodiments of the present invention. The VDM 10may also be communicably coupled to a third party headset and/ordispatch system, for example the FireCom™ system, and may be configuredto enter into the vehicle data record audio recordings from otherchannels and/or users (e.g. record in an ambulance VDM 10 audiocommunications from firefighters who have also responded to the sameemergency). The VDM 10 may be communicably coupled to a variety of audioor other multimedia systems in personal protection gear, such as facemasks, gloves, hazardous material suits, and/or helmets, according toembodiments of the present invention.
